Patent GB-357302-A (GB)
Title: Automatic change speed gear
IPC: F16H61/02
Filed: 1930-07-07
Abstract: 357,302. Variable-speed gearing. KAMPER, A. M., 62, Drummond Street, Carlton, Victoria, Australia. July 7, 1930, No. 20567. [Class 80 (ii).] An automatic change-speed gear comprises two epicyclic trains, one of which is operative for a fixed low speed and is combined with a detent and with a torque-reaction device which acts against the engaging spring 21, Fig. 1, by the friction clutch 16 of the other train, which effects variable higher speeds and solid driving. Secured to driving shaft 1 is sun gear 3 forming part of low-speed train 3, 4, 39. The carrier frame 10 of all the planet-gears is fast on the driven shaft 14. The high-speed train, like an arrangement described in Specification 322,589, [Class 80 (ii), Gearing, Variable-speed &c.], comprises stepped planets (not shown), connecting stepped planets 4 to a sun gear 6 fast on a sleeve 7 connected to a friction clutch drum 15, which tends to revolve rearwardly. Friction clutch shoes 16 carried by flywheel 2 on shaft 1 are normally pressed outwards into engagement with drum 15 by spring 21. The torque-reaction device acts through a lever 60 against spring 21 to disengage the solid drive and allow slip on lower ratios until the low-speed drive is effective. The reaction annulus 39 of the lowspeed train is connected through a frictional detent 43, Fig. 3, with a non-rotary ring 45, so that as the friction clutch engages, the ring 39 can turn freely forwards. Ring 45 is adapted to yield according to torque, and in so doing, through teeth 54 to turn a spiral gear 55 connected to the lever 60 acting against spring 21. To drive forwardly, control lever 31 is moved forwardly from the neutral position of Fig. 1 so as to bring the detent into action. The automatic change in forward speeds is then operative. To drive reversely, lever 31 is moved backwards so as to apply a brake 67 to an annulus 65.

Title: Liquid clarifying apparatus
IPC: C02F1/52
Filed: 1949-08-08
Abstract: <PICT:0671958/III/1> <PICT:0671958/III/2> <PICT:0671958/III/3> Apparatus for clarifying turbid liquids comprises a tank 20, Fig. 1, into the lower portion of which the turbid liquid is introduced through a conduit 36 while clarified liquid flows into a launder 27, the tank including agitating members 81 to 89 and 71 to 79 to bring about formation of a sludge blanket in the lower portion of the tank, and a pocket member 51 forming a quiescent <PICT:0671958/III/4> zone into which the sludge blanket normally overflows for facilitating withdrawal of excess solids, while the upper edge of the member 51 determines the minimum height of the blanket.  The apparatus is characterized in that the pocket 51 extends into a sump 19 in the tank bottom.  Blades 60 to 64 are also provided to impel settled solids into the sump 19 while backflow of the solids is minimized. The pocket member 51 comprises an open-ended cylinder secured to and rotating with four distributing arms 46 which are themselves secured to a hollow pillar 33. Incoming liquid passes through the conduit 36 formed in a fixed pillar 21 and out through openings 38 into an annular space 40 and then into the arms 46.  The latter are provided outside the pocket 51 with a series of discharge orifices 42, Fig. 5, pointing away from the direction of rotation.  Chemical reagents may be added from tanks 91, 92.  Flocs of solids constituting a sludge blanket are formed by the interaction of the members 81 to 89 secured to arms 46 and members 71 to 79 secured to four fixed arms 65.  The lowermost layers of sludge are raked by members 60 to 64 attached to arms 46 into the sump 19 through a narrow annular opening 54, and sludge rising in the tank above the level of the top of the member 51 overflows into it and is raked to the sump 19 by additional blades 57.  In the form shown in Fig. 3 no fixed central pillar is provided, and the sludge pocket 151, Fig. 9, engages with the rim 118 of the sump 116 by means of flexible strips 119 carried on its lower edge. Sludge from the tank floor raked towards the sump is pushed into it by the innermost rakes 164 which protrude inwards through openings 154 in both the wall of the pocket 151 and the strips 119.  The discharge orifices in this case may comprise holes each opening into a pocket formed between horizontal partitions across the lower portion of a vertical angle iron constituting an agitating member. The liquid issues in a backward direction from between the upper partition and the arm 141.  A further arrangement of discharge orifice is described.  Specification 545,913, [Group I], is referred to.

Title: Improvements in or relating to power-transmission systems for motor vehicles
IPC: B60K17/24
Filed: 1945-08-10
Abstract: 597,137. Yielding bearing supports. EVERNDEN, H. 1. F., and HARDY, F. J. Aug. 10, 1945, Nos. 20625 and 27046. [Class 12 (i)] For the support of a transmission shaft of a motor vehicle, such shaft being divided at an intermediate point with the interposition of a universal joint coupling, a bearing is provided adjacent the coupling and such bearing is mounted so as to be capable of movement in a plane normal to the axis of the supported shaft portion but .is so resiliently restrained that the restraint is greater in the vertical than in the horizontal direction. Fig. 1 shows the general layout of the drive with the front portion 24 of the transmission shaft supported by a ball bearing carried in a housing 32; the rear portion 25 of the transmission shaft is driven through a Cardan coupling 28. As shown in Fig. 2 the bearing housing 32 is supported on a chassis part 35 by a bracket 34 having a bolt 33 extending through a rubber bushing 36 secured in a lower part of the housing 32; the ball bearing 30 is mounted in the housing by a rubber ring 31. The housing is able to move in the horizontal direction transverse to the shaft by a pivotal movement about the axis of the bolt 33 with torsional deformation of the bushing 36 but only a small vertical movement is possible with compression of the bushing 36. Any oscillation may be damped by rubber buffers 37, Fig. 3, acting on lugs 38 extending from the housing or by friction plates 45, Fig. 6, engaged by rubber discs 46. Fig. 7 shows the bearing housing 32 supported by links 47 pivoted by means of torsionally deformable rubber bushings, the links being connected to the bearing housing on the lower side thereof whereby movement in the horizontal direction, by pivoting action, is easier than in the vertical direction. In the form shown in Fig. 9 the bearing housing 34 is secured by a metal strap 49 to a seating piece 50 supported from the chassis part by a spring loaded link 51 having torsionally deformable rubber bushings 36 to provide pivotal connections; the horizontal movement is allowed by the pivotal movement of the seating piece 50 about its pivotal connection but the lesser and more restrained vertical movement arises from torsional pivoting at both of the bushings. Figs. 11 and 12 are elevation and plan views showing the bearing housing 32 supported by arms 54 extending horizontally from its lower part which are fixed to plates 55 bonded to rubber blocks 56 carried on brackets 58 attached to the chassis. Movement of the bearing housing 32 is allowed by a deformation in shear of the rubber blocks 56 but horizontal movement is less restrained than vertical movement, due to the disposition of the arms 54: oscillations are damped by the brackets 58 being engaged by friction plates 60 on further arms 59 extending from the bearing housing 32. Stop arms 61 are provided at the top of the bearing housing to engage a chassis part and prevent excessive vertical depression.

Abstract: 1,156,354. EHT generation. RADIO CORPORATION OF AMERICA. 4 May, 1967 [23 May, 1966], No. 20889/67. Heading H2F. [Also in Division H1] In a line deflection circuit for a television receiver, the grid of a shunt regulating tube 90 for the E.H.T. supply is supplied by the voltage developed across an impedance 80 . . . 84 traversed by the beam current, and auxiliary winding RM of the line deflection transformer being interposed between the impedance and the E.H.T. winding PM so as to isolate the impedance 80. . . 84 from the high pulse potentials. As described, the line output stage 55 is coupled to deflection coils H, H<SP>1</SP> by means of transformer 60, of specified construction (see Division H1). The E.H.T. supply for the cathode ray tube 20 of a colour television receiver is derived by rectifying the flyback pulses in the high voltage winding PM and is stabilized by tube 90 shunted across the transformer 60. The flyback pulses at tapping D are differentiated at 101, 103, 105 and fed to the screen of the tube 90 and further differentiated by the self capacitance C and resistor 86 before being fed to the grid. This ensures that the tube 90 is conductive only during the leading edge of each flyback pulse, the current in the tube being controlled by the voltage developed by the beam current flowing in impedance 80. . . 84 so as to compensate for changes in beam current. A convergence winding 61 is included. Damping diode 62 and linearity adjustment 70 are provided. Components 63, 64, 65, 66 minimize radiation. An anti-hunt capacitor 85 is included.

Title: Improvements in or relating to statistical record controlled accounting machines
Inventor: BLAIN MAX
IPC: G06F7/498
Filed: 1953-07-29
Abstract: 744,331. Statistical apparatus, digital electric calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 29, 1953, No. 21021/53. Class 106 (1). A record controlled apparatus for the simultaneous entry of two or more amounts each represented by a series of electric pulses into an electronic counter, comprises means for supplying the pulses, a plurality of factor entry means for providing a connection between the counter and the supply means upon receipt of a further input pulse and a segmented delay line adapted to supply the further input pulse to all the entry means in succession during each of the series of pulses. Referring to Fig. 4, which shows the wiring diagram, it will be noted that 80 brushes are used in known manner to sense each card. Connections 4, between link hubs 5 and 6, are assigned to each brush to enter the readings into a single counter shown diagrammatically as Cu, Cd, Cc, Cm, Cdm. When a punched hole is detected by a brush, for example Bi a negative impulse is transmitted to terminal g of the corresponding trigger circuit Bij so that the left-hand tube of the trigger circuit becomes conductive while the second tube is made inactive. Each of the wires fi transmits an impulse whenever one of the nine rows 1 to 9 of the card passes under the leading brushes. These impulses are supplied by a cam contact 7 which makes at every new leading of holes punched in a row. When the contact 7 makes a positive pulse is transmitted to wire f 1 and with a certain delay to wire f2 and so on up to wire fp. To this end a delaying circuit of standard type is employed made up of coils 8 and condensers 9. The first impulse sent on wire f1 applies sufficient potential to the grids G1 of tubes T1u to T1m to enable the righthand tubes of the trigger circuits B1u to B1m to conduct when a punched hole has been detected. If, for example, the brushes detect in a row holes representing a number A1 the grids of the right-hand tubes in trigger circuit B1u and B1c are brought to a potential sufficiently low to make these tubes non-conductive. There follows a rise in potential of terminals K connected to the anodes of these tubes and grids G2 of tubes Tlu and T1c which are connected to terminals K of trigger circuits B1u and B1c-are brought to a value sufficient to allow tubes Ilu and T1c to become active as soon as a positive impulse is transmitted to wire f1. When such an impulse is received the potential of the anodes of tubes Tlu and T1c decreases. This drop in potential is then transmitted by wires eu and ec which effects registration of an impulse in the " units " and " hundreds " positions Cu and Cc respectively of the single counter. Specification 616,962 is referred to.
